Привет, я пытаюсь использовать giraph.
Я использую Имел oop -1.2.1 & Giraph-1.1.0
Пример * wordCount * oop хорошо работает. Но когда я пытаюсь использовать пример giraph "SimpleShortestPathsComputaion", это кажется успешным, но я не могу найти выходной файл (используя hadoop dfs -ls /output)
причина, по которой я думал, что это кажется успех, когда я проверяю http://master01: 50030 (jobTracker) 
команда здесь
giraph
$GIRAPH_HOME/giraph-examples-1.1.0.jar org.apache.giraph.examples.SimpleShortestPathsComputation
-vif org.apache.giraph.io.formats.JsonLongDoubleFloatDoubleVertexInputFormat
-vip /input/tiny_graph.txt
-vof org.apache.giraph.io.formats.IdWithValueTextOutputFormat
-op /output
-w 2
Вот журналы
